N2 - An influence of localized holes on magnetic properties of the CuO2 planes in quasi-2D antiferromagnets (La2CuO4, YBa2Cu3Oδ+x etc.) is studied. It is demonstrated that the hole localized on the bond connecting Cu2+ ions gives birth to frustration which in a wide range of parameters behaves as the two-level system with the energy E≪J, where J is the exchange interaction of the neighbouring copper spins. As a result for T≦E the spin-wave energy may noticeably decrease even at a low concentration of the holes c if the parameter cJ|E| is not small.
